METALLICA (Stern) Plastic shield set

Stern METALLICA pinball machine 5 piece set of clear playfield
plastic shields.

(All protectors are clear, image is tinted for contrast.)

Plastic protectors mount beneath flat artwork plastics and
protrude about 1/8 inch around the perimeter of each plastic
piece.

They're made from impact resistant PETG (Polyethylene
Terephtalate Glycol-modified) plastic to prevent ball damage to
artwork plastics.

Thin enough to mount with existing fasteners, they are also clear
and cosmetically unobtrusive.
